Background: Do In Seung Gi-Tang (DISGT) is an herbal mixture of traditional Korean medicine that is composed of Rheum undulatum Linne, Prunus Persica (L.) Batsch, Conyza canadensis L., Cinnamomum Cassia Presl, and Glycytthiza uralensis Fischer (8: 6: 4: 4: 4 ratio). We investigated the effect of DISGT on vascular inflammation and lipid accumulation in apolipoprotein E-deficient (ApoE(-/-)) mice. Methods: ApoE(-/-) mice that were fed a high-fat diet (HFD) were treated with DISGT (300 mg/kg/day) or statin (10 mg/kg/day) for 16 weeks. Serum lipid levels were analyzed. Oil Red O staining was used to evaluate atherosclerotic lesions and lipid accumulation in the aorta and liver, respectively. The expression of adhesion molecules (intercellular adhesion molecule-1 [ICAM-1], vascular cell adhesion molecule-1 [VCAM-1], and E-selectin), fatty acid synthase (FAS), adenosine monophosphate-activated protein kinase (AMPK), and acetyl-coA carboxylase (ACC) in the aorta or liver tissues was measured by western blot analysis. Lipid synthesis and inflammatory responses were assessed by immunohistochemistry and hematoxylin & eosin staining, respectively. Results: Treatment of HFD-fed mice with DISGT significantly lowered body weight, liver weight, and the levels of lipids, including total cholesterol, low-density lipoprotein-cholesterol, and triglycerides. Glucose levels were also lowered. In the aorta, DISGT attenuated atherosclerotic lesions and reduced the expression of ICAM-1, VCAM-1, and E-selectin. Moreover, DISGT decreased lipid accumulation, inflammatory responses, and FAS levels, and it activated AMPK and reduced ACC expression in liver tissues. Conclusions: The beneficial, anti-lipolytic, and anti-inflammatory effects of DISGT were mediated by the AMPK pathway. As a result, the expression of inflammatory factors was reduced. Our data provide evidence that DISGT may have strong therapeutic potential in treating vascular diseases, such as atherosclerosis.
